FYI, the setlists available on Phish.com also include information about the house music playing as fans walked into the venue, at setbreak, and as fans exited the venue. For example, at Wrigley Field on June 25, 2016, fans heard the following:
Ralph Stanley – Best of the Best
Hopeton Lewis – Take It Easy with the Rock Steady Beat
Allen Toussaint – Southern Nights
The Avalanches – Since I Left You
The Funkees – Dancing Time: The Best of Eastern Nigeria’s Afro Rock Exponents 1973-77
Steve Goodman “Go Cubs Go”
In addition, Julia Mordaunt of Phish Inc. has very generously created a breathtaking spotify playlist of the music performed during walk-in, setbreak, and walk-out (that's available on Spotify). Check it out here.
